MÔ TẢ CHUNG
Thiết bị cầm tay dùng để phát hiện phóng điện cục bộ bằng công nghệ siêu âm cho phép phát hiện và định vị vị trí PD. Thiết bị bao gồm 64 cảm biến siêu âm microphone phù hợp để đo trong trạm biến áp và các thiết bị cao và trung áp khác như:
Dao cách ly, sứ đỡ, đầu cáp, đầu sứ máy biến áp, TI, TU, chống sét van, …
Với công nghệ siêu âm (SoundSight) kết hợp giữa hình ảnh thật và âm thanh cho phép người dùng có thể quan sát và phát hiện vị trí xảy ra PD trực tiếp trên màn hình
chính của thiết bị
Công nghệ định vị trực quan nhanh chóng chỉ ra khu vực nghi ngờ có sự cố:
• Dạng cầm tay, gọn nhẹ
• Phần mềm phân tích trực quan trên máy
• Tích hợp công nghệ lọc nhiễu có thể dễ dàng thao tác trên máy
• Màn hình cảm ứng LCD
• Hỗ trợ chụp ảnh hoặc qoay video vị trí nghi ngờ có sự cố
• Công nghệ phối trộn phổ âm thanh với ảnh thật giúp phát hiện vị trí có rủi ro
(Sound Map)
• Đánh dấu vị trí nghi ngờ sự cố (Spot maker)
• Phần mềm giúp thống kê biểu đồ (Trend graph theo dạng dB hoặc Hz)
FLIR E4, E5-XT, E6-XT, and E8-XT are powerful, cost-effective, easy-to-use troubleshooting tools for building, electrical, and mechanical applications.
With four resolution options—up to 320 × 240 infrared pixels—and the ability to accurately measure temperatures from -20°C to 550°C/-4°F to 1022°F (E6-XT and E8-XT), the Ex-Series has models to fit your target size, working distance, visual detail needs, and budget.
All models include MSX® technology for extraordinary thermal imaging detail
. Wi-Fi connectivity to smartphones and tablets via the FLIR Tools® Mobile app makes sharing images and sending reports from any location easier, enabling you to make critical decisions faster.
With Ex-Series cameras, you can gain the competitive advantage by providing clients with thermal images that clearly reveal the source of electrical, mechanical, and building-related problems.
